A major challenge associated with the implementation of CL initiatives lies with their economic and financial long-term success. In this context, the business model concept can support assessing the business side of stakeholders’ decision-making processes as major determinants for such success. The purpose of this work is to overcome the...

User centered design of products, services, and systems is widely accepted. Numerous user research tools and methods exist to engage users and gather users’ insights to inform the design process. Unfortunately, time, effort, and expense of many tools often delay the availability of user insights. To address this concern, a series of studies...

The subject of this academic research thesis is a methodical approach on the complex problem-solving process of structural conceptual design.For this relatively unexplored problem, an exploratory research is conducted by systematically zooming in from the whole to the part and from coarse to fine. The so explored methodical approach on...

Function modelling is proposed in the literature from different disciplines, in interdisciplinary approaches, and used in practice with the intention of facilitating system conceptualisation. However, function models across disciplines are largely diverse addressing different function modelling perspectives and using different structures and...

Large-scale agent-based social simulation is gradually proving to be a versatile methodological approach for studying human societies, which could make contributions from policy making in social science, to distributed artificial intelligence and agent technology in computer science, and to theory and modeling practice in computer simulation...

Optimisation or real time control (RTC) studies in wastewater systems increasingly require rapid simulations of sewer systems in extensive catchments. To reduce the simulation time calibrated simplified models are applied, with the performance generally based on the goodness of fit of the calibration. In this research the performance of three...

The primary challenge underscored and dealt with was how to represent the product’s or system’s use environment and processes and to communicate ideas and envisaged use contexts effectively at the fuzzy-front early stages of the design process. The work focused specifically on complex products or systems with physical, software and/or cyber...

Objectives This paper proposes a conceptual model of the complex relationships between travel behaviour and health. In addition it gives a research agenda providing an overview of challenges for future research. Methods We review the relevant literature in the areas of public health, land use and transportation that address issues related to...

The Ornicopter concept is a single-rotor, tailless configuration. By actively flapping its blades, the Ornicopter rotor can propel itself to rotate, and hence does not need a tail rotor. In previous research, the Ornicopter concept has been compared with the Bo-105 conventional helicopter from various aspects, while the Ornicopter has the same...

Interdisciplinary system development requires the integration of diverse expertise to combine different engineering technologies and—increasingly often—services, in order to provide users with expected value and desired functionality in newly developed products. Failure to achieve integration of disciplines can result in design errors posing a...

About 40-50% of global raw materials are currently used in the building industry in the assembly/construction phase and in the use phase of the building and are responsible for 40-45% of total worldwide anthropogenic carbon dioxide emissions (Huovila [5]). These problems have led to the development of legislative policies, regulations and...

The adoption of computation in the building industry has led to the development of a range of tools intended for design. Although commonly used for detailed analysis (FEA) and documentation (CAD/BIM), few tools address the needs of the early design stages for flexibility and quick, insightful feedback and documenting the justification of design...

Currently, in the conceptual envelope design of sports facilities, multiple engineering performance feedbacks (e.g. daylight, energy and structural performance) are expected to assist architectural design decision-making. In general, it is known as Building Performance Optimization in the conceptual architectural design phase. Essentially, it...

Innovative engineering design shapes the development of novel technologies and is ethically as well as socially relevant, because it affects what kind of possibilities and consequences will arise. A major challenge in engineering design work on innovative technologies is the multitude of uncertainties in the form of known unknowns, unknown...

This paper presents a review of existing research, projects, developments and applications in the domain of design tools for conceptual structural engineering. The availability of these tools and research into software for conceptual structural design stages has shown a number of interesting developments over the last past few years. The purpose...

This paper presents a proposal to employ the design computing methodology proposed as StructuralComponents (Rolvink et al [6] and van de Weerd et al [7]) as a method to perform a digital verification process to fulfil the requirements related to structural design and engineering as part of a building design. In current design and engineering...

This paper presents the results of the investigation into the possibilities for the implementation of a Building Performance Simulation design toolbox during the early stages of façade design, based on the sustainability-open framework [2]. The background and development of the EnergyFacade toolbox will be discussed which has been built on the...

Even without uncertainty about the model structure or parameters, the output of a hydrological model run still contains several sources of uncertainty. These are: measurement errors affecting the input, the transition from continuous time and space to discrete time and space, which causes loss of information about the input, discretization of...

The tail rotor of conventional helicopters has always been considered a necessary 'evil'. It is necessary to counteract the reaction torque of the engine and to control the helicopter in yaw but it consumes substantial power, has only marginal control authority under unfavourable wind conditions, and it is noisy, vulnerable and dangerous. A...
